Thanks for reply Sorry for my stupid english skill :)
Question 1: Does IPP have a pseudo inverse function?
Question 2: If doesn't exist in IPP, How operate pseudo inverse using IPP?
Are you looking for the function like matlab discription, /* PINV(A) produces a matrix X of the same dimensions as A' so that A*X*A = A, X*A*X = X and A*X and X*A are Hermitian. The computation is based on SVD(A) and any singular values less than a tolerance are treated as zero. The default tolerance is MAX(SIZE(A)) * NORM(A) * EPS(class(A)). */
Then IPP haven't direct function, but ipp should be have oneSVD function, you may check it in ippm or ipps manual. Or check IPP's sister library, math kernal library (MKL), which provide more math routines in it.
